Is it possible

[GWS.Arkansas]

I have a hypertherm 85. I use 45 amp fine cut consumables. I am wanting to buy some files from Jason. The clocks. Will I be able to turn my machine down low enough to be able to cut them?

How thick of material are you planning on using?

The Powermax 85 can cut 26 gauge with good results if you want to go that thin. Look at the cut charts in your operators manual, they are very clear on material type, material thickness and all of the setting fro cutting.

I have the 65 im pretty sure the charts the same

for 20-26 gauge you run 40 amps

for 18-10 you run 45 amps

the charts are in youre owners manual and online.

you should have no problem and you will be impressed by the hypertherm.

they are AWESOME !!!

I have discussed this with Jason a couple of times as I know quite a few others have too so don't shoot me down for saying it as I see it.

I find I have to alter most of Jason's designs to gain extra clearance between cuts especially at start points. When I draw something myself I allow 3mm or 1/8" minimum between cuts to allow for the cut (my kerf width on 16 gauge is 1.3mm), Jason claims you only need 1/16" between cuts which you can sort of get away with sometimes but if you have two pierces next to each other suddenly there is no metal left there or if there is it is very flimsy.

I have all of Jason's collection and find it excellent for producing pieces, I do however make sure I run through the drawing first to ensure there is enough clearance. As long as you realize you may have to adjust some line lengths and end points in some files you wont be disappointed in what you can achieve.

In answer to your original question, some of Jason's clock files have a lot of detail so it's probably very relevant to what size you anticipate cutting them. If you wish to cut a clock at 6", I think your going to struggle no matter what plasma you have. At drawn size you may have to change a few end points. Why not download some of his free sample http://freedxf.com/cnc-artwork/branch-frame-clock-14b and try, a guy wouldn't offer so many free files if he wasn't confident in his product.

Has anyone seen any teeny weeny plasma cutters that have a nozzle much smaller than a Finecut, and correspondingly lower amps. I tried turning down the amps on my Finecut nozzles and reducing the cut speed but the cut just was not nice. I'm guessing the arc simply loses its density.

A mini plasma cutter like I mentioned could be good for fine work on thinner plate. Yeah the Finecuts are good but having something smaller would also be good.

remember that you cannot blame just the plasma cutter for ugly cut quality. It is only part of the equation, the ability to stay on path and maintain cut speed is a function of the cnc machine's capability, and the need for maintaining the correct height is a function of the torch height control system, and proper part drawings with adequate clearances, proper cut path order (to stabilize heat input) are all critical.

The Finecut parts in a Hypertherm system will operate well down to 20 or 25 amps. You will need to do a little experimenting using the capability of your particular cnc/THC/software in order to fine tune the process for best performance.

Bottom line is that some machine combinations have the ability to cut very fine detail better than others.
